(3) EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS Beginning on the effective date of this permit and lasting through the expiration date, the Permittee is authorized to discharge from outfall 002 (boiler blowdown, once -through cooling water, and treated wastewater from outfall 001) Such discharges shall be limited and monitored by the Perniittee as specified below: EFFLUENT LIMITATIONS -...,;MONITORING REQUIREMENTS �- PARAMETER ----- - -------- Monthl W.

Upstream shall be at the Permittee's river pump station; downstream shall be at the boat ramp approximately 4500 feet downstream at Prospect Hall Landing. As a participant in the Cape Fear River Basin Association, the instrearn monitoring requirements as stated above are waived. Should your membership in the agreement be terminated, you shall notify the Division immediately and the instream monitoring requirements specified in your pen -nit shall be reinstated. 2. The temperature of the effluent shall be such as not to cause an increase in the temperature of the receiving stream of more than 2.8°C and in no case cause the ambient water temperature to exceed 32°C. 3. Daily shall be defined as every day except Saturdays, Sundays, and legal holidays. Instream temperature sampling shall be conducted weekly. 4. The samples for fluoride shall be taken downstream of the 001 discharge, unless or until, all neutralized Nafion area streams are discharged entirely into the cooling water outfall, 002. Instream fluoride monitoring shall be conducted monthly and shall coincide with effluent monitoring. 5. PFOA (Perfluorooctanoic acid) - The Cape Fear River water intake may be sampled for PFOA on a monthly basis and reported as an upstream parameter in DWQ Form - MR-3. THERE SHALL BE NO DISCHARGE OF FLOATING SOLIDS OR VISIBLE FOAM IN OTHER THAN TRACE AMOUNTS. * DEQ-CFW-00082594 The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentration of 3.3%. The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North Carolina Phase It Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The tests will be performed during the months of February, May, August, and November. Effluent sampling for this testing shall be performed at the NPDES permitted final effluent discharge below all treatment processes. If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the two following months as described in "North Carolina Phase 11 Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The chronic value for multiple concentration tests will be determined using the geometric mean of the highest concentration having no detectable impairment of reproduction or survival and the lowest concentration that does have a detectable impairment of reproduction or survival. The definition of "detectable impairment," collection methods, exposure regimes, and further statistical methods are specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the parameter code TGP313 for the pass/fall results and THP3B for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent- to the following address: Attention: Environmental Sciences Section North Carolina Division of Water. Quality 1621 Mail Service Center Raleigh, North Carolina 27699-1621 Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later than 30 days after the end of the reporting period for which the report is made. Test data shall be complete, accurate, include all supporting chemical/physical measurements and all concentration /response data, and be certified by laboratory supervisor and ORC or approved designate signature. Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream. Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the facility name, permit number, pipe number; county, and the month/year of the report with the notation of "No Flow" in the comment area of the form. The report shall be submitted to the Environmental Sciences Section at the address cited above. Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be required during the following month. Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water Quality indicate potential impacts to the receiving stream, this permit may be re -opened and modified to Include alternate monitoring requirements or limits. NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism survival, minimum control organism reproduction, and appropriate environmental controls, shall constitute an invalid test and will require immediate follow-up testing to be completed no later than the last day of the month following the month of the initial monitoring. DEQ-CFW-00082595 This permit shall be modified, or revoked and reissued to incorporate additional toxicity limitations and monitoring requirements in the event toxicity testing or other studies conducted on the effluent or receiving stream indicate that detrimental effects may be expected in the receiving stream as a result of this discharge. The permittee shall not use any biocide except those approved in conjunction with the permit application. The permittee shall notify the Director in writing not later than ninety (90) days prior to instituting use of any additional biocide used in cooling systems which may be toxic to aquatic life other than those previously reported to the Division of Water Quality. Such notification shall include completion of Biocide Worksheet Form 101 and a map locating the discharge point and receiving stream. DEQ-CFW-00082596 DEQ-CFW 00082597
